Pterospermum yunnanense

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Pterospermum yunnanense faces severe population decline primarily due to extensive deforestation and agricultural expansion throughout its limited range in Yunnan Province, China. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while logging for timber and conversion of forest areas to agricultural land continues to reduce available habitat. Climate change poses an additional threat by altering the montane forest conditions this species requires for survival.
